3.5 Wiring the Fault Alarm Contact
The fault alarm contacts are in the middle of the terminal block connector as
the picture shows below. Inserting the wires, the Industrial Ethernet Switch
will detect the fault status of the power failure and then forms an open circuit.
The following illustration shows an application example for wiring the fault
alarm contacts.

1. The wire gauge for the terminal block should be in the range
between 12 and 24 AWG.
